International Conference on Climate Change and its Impact on Himalayan Region to be held in India

The Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital is to conduct an International Conference on Climate Change and its Impact on Himalayan Region. The conference is to be held between September 14 and September 16, 2020.

Highlights

The conference is to focus on rapid increase in air pollution due to urbanisation, industrialisation and its impact on global air quality, cloud formation, visibility degradation, radiation budget, monsoon patterns, human health, water availability, glaciology and Himalayan climate.

The conference will also focus on the following themes

  • Climate change impacts on Himalayan Glaciers
  • Growing pollution in Indo-Gangetic plains, Himalayan glaciers and central Gangetic Himalayan region.
  • Aerosols, water resources and their Climate interaction over Himalayas.

Significance of the conference

  • Atmospheric Aerosols called the Particulate Matter are suspended in the air. Due to rapid economic growth, urbanisation and industrialisation, the aerosols in the atmosphere are rapidly increasing.
  • The northern Indo-Gangetic plains and Himalayan region are the major global hotspots of pollution due to anthropogenic emission.
  • The regions receive frequent dust storms during pre-monsoon period.
  • The air quality during post-monsoon and winter are declined due to bio fuel burning.
  • The conference is also important to find solution for black carbon deposition in the Himalayan glaciers

Black Carbon Deposition in Himalayan Glaciers

In March 2020, the researchers at the Wadia Institute of Himalayan Geology found that the concentration of black carbon has almost doubled in the last few years mainly due to forest fires and agricultural burning. The following were found by the researchers about Himalayan Glaciers

  • The concentration of black carbon increases in summer months. It was 4.62 micro grams per cubic metres during summer.
  • The concentration of black carbon comes down to 2 micro grams per cubic metre during non-summers.

Black Carbon

It is an aerosol suspended as fine solid particle or liquid droplet in air. It is considered as the second most important anthropogenic agent of climate change. It is emitted from coal fired power plants, gas and diesel engines.
